I'm trying to build the following and get the following error. "An error occured: You are not allowed to build this facility, either because your faction does not have the datacard, or the terrain prevents you." The terrain is not preventing it and my faction as the DC.

You also have to build it for the faction and you have to have the priv to do so. You cant build restricted buildings for your self. You build it for the faction and then you have to have the faction make it over to you
